It is almost impossible to maintain this temperature specially during summer when the atmospheric temperature rises even up to 50"C. In view of the above, IS 6359: 1971 `Method for conditioning of textiles' specifies a temperature of 27 t 2°C for conditioning of the test specimens for the tropical countries like India. This standard is being followed in testing of textiles and other products since decades. The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words `International Standard' or `European this standard, they should be read as `Indian Standard'. b) Standard' appear referring to Comma (,) has been used as a decimal marker, while in Indian Standards, practice is to use a point (,) as the decimal marker. the current In reporting the results of a test or analysis made in accordance with this standard, if the final value, observed or calculated, is to be rounded off, it shall be done in accordance with IS 2 : 1960 `Rules for rounding off numerical values (revised)'.
